At least they are not Christ's friends, and he, as follower of the Master, finds no sympathy among them in his new life.

He must stand alone in his discipleship, conscious all the while that unfriendly eyes are upon him.

Many a young or older Christian finds it very hard to be the only one to stand for Christ in the circle in which his daily work fixes his place.
This aloneness puts upon one a great responsibility.

For example, you are the only Christian in your home.

You are the only witness Christ has in your house, the only one through whom to reveal his love, his grace, his holiness.
